ABSTRACT:
A smoke stack, which discharges contaminated gases, is provided with a plenum chamber, at its end, formed of one or more stacked modules. Each module includes a hollow cylindrical housing, from which protrudes, in various radial directions, a plurality of ducts, each being provided with a nozzle at its end. The nozzle has a central passageway through which a portion of the gases pass and is discharged into the atmosphere, and a second passageway which directs the air around the discharging gases for imparting a swirling action to the commingled gases. An ultra low volume of treatment fluid, usually a liquid chemical, is progressively discharged into the central passageway so that fog is generated as the gases and liquid emerge. Relief valves for the gas discharge into this fog. An accumulator tank at the top of a chamber or a metering pump supplies the liquid.
In the process, the stream of contaminated air is subdivided by the ducts and again subdivided by the nozzles, the liquid being fed to the central passageway of the nozzle through which a subdivided portion of air passes. Another subdivided portion of the air causes the mixture emerging from the passageway to swirl. Various treatment liquids are discussed.
